M5lp 1206 017 Engine Swap Guide Heavy Rotation

Dropping a 5.4-liter engine from a Ford truck/van has long-been equated with replacing a Fox's pushrod 5.0 with a 351W powerplant. Like the 351W, a Two-Valve 5.4-liter modular provides immediate, increased torque to Ponies of Two-Valve 4.6 heritage. One of the nuances in this swap is that a 5.4's taller deck height and the need for intake-adapter plates that are 1 to nearly 2 inches thick, which can actually raise the throttle body almost 2-1/2 inches higher. Removing a section of the stock hood's bracing or adding a taller, aftermarket hood, creates the necessary clearance.
